After removing and reinstalling the dash, the EPS no longer functions. The EPS indicator turns on with ignition and stays on. No DTCs appear using an OBDII scanner or on Kpro.

Clues (?):
- The single-pin brown plug located above the EPS control unit and below / behind the ECU is not connected to anything... I do not see a male connector for it on the harness.
- The SRS harness and control box have been removed.
- A bad ground under the passenger seat caused total loss of power while driving. The EPS had NOT been working prior to this.
